Jean de Breuilly was a 16th-century French adventurer from Honfleur. In 1528, he left for an expedition to Asia, to seek the whereabouts of the expedition of Pierre Caunay, but was unable to find it.[1]
Jean de Breuilly stopped at Zanzibar in March 1528.[1] He then arrived in the harbour of Diu on the Indian coast, but there his ship was seized by the Portuguese.[1]
His ship seems to have been called the Marie de Bon Secours, also named Grand Anglais.[2]
